<p>P-medium IMO - it's an ICE but you have to do it intentionally</p>

<p>Yeah, that sounds good. Plus the ICE goes back to Rust 1.33.</p>

<p>You really have to do it intentionally since removing the call to <code>core::panic!</code> (which is not allowed in the position it was in) doesn't ICE (but it does error):</p>

<p>the issue is fixed on master before prioritizing, just dropped the <code>I-prioritize</code></p>
